Menzi Muck M540 Tunnel Excavator
The Menzi Muck M5 all-terrain mobile excavator is the pocket-rocket of the tunnelling industry. The M5 class machine has been utilised on many tunnel construction projects and is an ideal partner for schemes with a combination of escalator drives, cross passages and chambers. The M540/545 gives high mobility through the site whilst being capable of working on very steep gradients and carrying the most productive of attachments.
With low weight and high drive power combined with unrivalled lifting forces and hydraulic power the M5 series is capable of carrying and driving attachments more commonly seen in the 30 tonne weight class.
The Menzi Muck M5 is known within the tunnel industry for being the most productive power unit for road-header or rockwheel operation in its class and can also be combined with heading buckets, drilling equipment and shotcrete manipulators to give a high power, high utilisation machine.
